Energy Storage System
An energy storage system uses energy produced by a primary energy generation assembly beyond a peak primary use production limit to increase potential energy in a secondary energy generation assembly for later use to supplement energy produced by the primary energy generation assembly during periods of less than peak energy production by the primary energy generation assembly. The system includes a primary energy generation assembly having a peak primary use production limit and a peak total production limit. The peak total production limit is greater than the peak primary use production limit. A secondary energy generation assembly utilizes gravitational transfer of a weighting material from an elevated position to a lowered position to produce electrical energy. The secondary energy generation assembly is selectively actuatable such that energy generated by the secondary energy generation assembly supplements energy produced by the primary energy generation assembly.
The disclosure relates to energy storage devices and more particularly pertains to a new energy storage device for using energy beyond an upper usable limit to increase potential energy in a secondary energy generator to supplement energy produced by the wind generator during periods of less than peak energy production.
SUMMARY OF THE DISCLOSUREAn embodiment of the disclosure meets the needs presented above by generally comprising a primary energy generation assembly having a peak primary use production limit and a peak total production limit. The peak total production limit is greater than the peak primary use production limit. A secondary energy generation assembly utilizes gravitational transfer of a weighting material from an elevated position to a lowered position to produce electrical energy. The secondary energy generation assembly is selectively actuatable such that energy generated by the secondary energy generation assembly supplements energy produced by the primary energy generation assembly. Energy produced by the primary energy generation assembly in excess of the peak primary use production limit is utilized to move the weighting material from the lowered position to the elevated position.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The secondary energy generation assembly 14 comprises a first storage tank 30 positioned holding the fluid 28 at the elevated position 24. The first storage tank 30 may be either man made of conventional design or may be natural such as a pool, pond, or lake, which may also be man made if no natural water source is present near the elevated position 24. A second storage tank 32 is also provided holding the fluid 28 at the lowered position 22 until such time as excess energy production is available from the primary energy generation assembly 12 to power a pump 34 fluidly coupling the second storage tank 32 to the first storage tank 30 such that the pump 34 transfers the fluid 28 from the second storage tank 32 to the first storage tank 30 when activated. The second storage tank 32 may be considered to comprise not only a man made tank according to a conventional definition or a natural water resource into which water can be deposited and from which water can be taken. The natural water resource may be substantially still such as a pond, lake, or the like, or may be moving such as a stream, river, or the like.
A generator 36 is driven by gravitational transfer of the fluid 28 from the elevated position 24 to the lowered position 22 using a plurality of chambers 38. Each of the chambers 38 holds the fluid 28 as the fluid 28 is transferred from the elevated position 24 to the lowered position 22. A track 40 extends between the elevated position 24 and the lowered position 22. The track 40 may be a single linear extent 44 as shown in
A pulley 52 is operationally coupled to the generator 36 such that rotation of the pulley 52 activates and drives the generator 36. A cable 54 is engaged to the pulley 52 wherein movement of the cable 54 rotates the pulley 52. Each of the cars 50 is coupled to the cable 54 wherein movement of the cars 50 from the elevated position 24 to the lowered position 22 moves the cable 54 such that the pulley 52 is rotated.
In use, the system 10 provides for a method 60 of storing energy for later use to supplement energy produced by the primary energy generation assembly 12 during periods of less than peak energy production. The method 60 comprises a step 62 of having the primary energy generation assembly 12 as described above. Another step 64 is using energy produced by the primary energy generation assembly 12 in excess of the peak primary use production limit to move the weighting material 20 from the lowered position 22 to the elevated position 24. Another step 66 is actuating the secondary energy generation assembly 14 and the secondary energy generation assembly transferring the weighting material 20 from the elevated position 24 to the lowered position 22 to produce electrical energy. Yet another step 68 is supplementing energy produced by the primary energy generation assembly 12 with the electrical energy produced by the secondary energy generation assembly 14. The method 60 may further comprise the step 66 comprising actuating the secondary energy generation assembly 14 more specifically during periods of less than peak energy production by the primary energy generation assembly 12. Still another step 70 is pumping the weighting material 20 from the lowered position 22 to the elevated position 24 for storage until the weighting material 20 is used to facilitate the secondary energy generation assembly 14 generating energy to supplement the primary energy generating assembly 12. The method 60 may further include steps less explicitly described or implied in the above description of the system 10.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
